Arterial saturation (SaO₂) and fractional tissue oxygen extraction (FTOE).

Arterial saturation was similar between groups and over time. Renal and cerebral FTOE was lower in FGR compared to controls. Renal FTOE, but not cerebral FTOE, behaved differently over time. Significant group differences are shown and * indicates whether the groups behaved differently over time (pinteraction<0.05). ∆ indicates the slope per 3 hours interval. Data shown as mean ± s.e.m.
